Them!

Them stars James Whitmore as New Mexico Police Sgt. Ben Peterson who discovers a little girl wandering in the desert. He finds her trailer ripped apart and her parents missing. Casts of the strange footprints found at the crime scene are sent to a lab where they catch the attention of father/daughter doctors Medford (Edmund Gwenn and Joan Weldon) who come to New Mexico along with FBI agent Robert Graham (James Arness) to investigate. Dr. Medford has a theory but won't tell Peterson or Graham until he has more proof.

If you are a fan of sci-fi films, Them is one of the four essential sci-fi films of the 1950s along with The Thing, Day the Earth Stood Still, and Invasion of the Body Snatchers. It's part crime story, part sci-fi, part horror with crisp dialog and it moves along at a brisk pace. Veteran director Gordon Douglas put together a solid cast of actors and the characters are totally believable. The story is interesting and the sets are outstanding.

Them was a box office hit in 1954 and it still holds up today if you can forgive the special effects. Them is a movie where any remake would always pale with the original. Highly recommended.
